Resolution: NXPowerLite is registered but it is not reclaiming any space as indicated on Quick Scan report – Neuxpower

After registering NXPowerLite is it possible that you run the software and it will not reclaim any space as indicated in the Quick Scan report. There are generally two reasons why this is happening; the software is not configured correctly or a misunderstanding of how Quick Scan estimates space savings.

How do I ensure I have correctly configured NXPowerLite?

1. Service permissions

The NXPowerLite windows service is not configured with a user account that can access some or all of the configured folders. By default, NXPowerLite is configured with the Local System Administrator account. This account rarely has access to network drives and shared folders.

Resolution:

Ensure the 'NXPowerLite File Server' Windows service is configured with a user account that has full permission (Read, write, update & delete) to each of the configured folders/drives. For detailed instructions see Configuring the NXPowerLite Windows Service.

2. Ensure configured Files to include profile does not exclude files by type or date

It is possible to exclude certain file types and also by their last modified date.

Resolution:

For the configured folders please ensure that you check for the existence of the file types configured. Also, ensure you are not limiting files by date. If unsure use the default All files profile for your folders.

See Files To Include for a more detailed explanation of settings.

Is the Quick Scan report relevant to my data?

Once you have run NXPowerLite Server over your data, the Quick Scan estimate becomes irrelevant.

The Quick scan report is intended to give users a very quick estimate of how effective NXPowerLite will be on uncompressed user data. In order to be 'Quick', it is a read-only scan that notes file extensions of all files in the selected folders to build a list of possible supported files. It then estimates the space savings based on average reductions from millions of customers files.

The scan cannot determine whether files have already been compressed by NXPowerLite so it will still estimate space savings for compressed data.

For example:

You run NXPowerLite Quick scan over a set of 100GB of uncompressed data the report estimates it will save you 50GB.
Then you run NXPowerLite on the File Servers on the data and it compresses the data to 50GB.
Next, you run a quick scan of the compressed data, it may estimate 15GB of savings for the data.
However, if you try to compress that same set of data again with NXPowerLite Server it will not reduce as all the files are already compressed.
